tion, such as will enable others skilled in the art to which it pertainsto make and use the same, reference beinghad. to the accompanyinobviating a great waste of power in that 'ing drawings, which form apart of this specification.

Our invention relates in general to cartrucks, and more particularly toa truck upon which is mounted an explosive-engine.

As explosive-engines are more economical in operation than other formsof motors, it is desirable to employ them for propelling street andrailroad cars, especially on suburban and interurban railroads.

The use of explosive-engines as car-motors has advantages over electricpropulsion by dispensing with costly power plant, machin- -5 ery, poles,and wires andeconomizing not only lnthe cost of the power consumed, butalso when the car stops the manufacture of power also ceases. It alsohas advantages over steam propulsion by not only economizing in the costof the power 'consumed, but also by obviating-the use of costlylocomotives, and it used as provided in our invention it obviates theunsatisfactory construction sometimes adopted in steam propulsion inwhich a portion of the interior of the car-body is occupied by theboiler and'machinery.

All parts of the propelling mechanism should be below the bottom of thecar-body.

The primary object of our invention is to provide a self-propelledcar-truck adapted to pivotally support the car-body, with a multi-,ple-cylinder explosive-engine supported entirely upon the truck andoperatively connected to all wheels of the truck through'dilfen entialtransmission mechanism, whereby the car may be operated in eitherdirection at .will and the speed of -the car may be varied with orwithout varying the speed of the engine, the engine and all propellingmechanism being below thelevel of the car-body, thus not interferingwith the car-body itself and also aflording free radiation of the heatfrom the engine without unnecessarily heatingthe car.

A further object of our invention is to provide a self-propelledcar-truekwherein the engine and truck-frame are connected rigidlytogether, but having a-flexible connection between the engine and thetruck-wheels, thus permitting the wheels and axles to have anindependent vcrtical'movement to adapt them-- selves to any inequalitiesin the surface of the rails withoutsubjecting the engine and its partsto sudden shock, having also a flexible comparatively simple inconstruction, efiicient in use, and economical in operation, couform'ing' in shape and dimensions to usual railroad practice and being atruck which can readily be adapted to any ordinary railroad-car bodywith practically no change in the car-body itself. 7 I

Our. invention, generally described, consists inders intermediate'of theaxles and truckwheels, a crank-shaft parallel to the axles and locatedbetween opposed cylinders of the I: I "r; a); g I engine, a differentialtransmission gearing mounted on one axle, flexibly operative con-Jnections, between; the crankshaft and traias;- mission-1 glean;Sprocket? wheel's fixed; tp the 5 axles between the wheels and.axle-boxes,

These braces arepreferably secured by bolts'or other fastening devices beneath theinturned flanges of the-end sills of the truck-frame and extend beneaththecrank-casing' of the engine.

The manner of constructing our improved 1 invention will be readilyunderstood from the foregoing description, and its operation may*bebr'iefly described as follows: The reciprocations of the pistonswithin the engine-cylinders rotate the crap k-shaft D, which in turn,"through the sprocket E and sprocket-chain ..E, imparts rotary motion tothe transmission the truck, and as the wheels themselves are permittedvertical movement independent of the truck, engine,.or car-body afacility of movement of the various parts results on account of theflexibly-operative mechanism.

From the foregoing description it will be observed that we have inventeda car-truck so constructed that space is provided for amultiple-cylinder engine, which is directly supported upon the truck andbelow the truckbolster and transom. It will be further ob-* served thatin our invention both axles of the truck are connected to the motor, sothat all -01 the wheels of the truck are drivers.

, While we have described more or'less precisely the details ofconstruction 'wedo notwish to be understood as limiting ourselvesthereto, as we contemplate changes in form, the proportion of parts, andthe substitution of equivalents 'as circumstances may suggest or renderexpedient without departing from the spirit of our invention.
